i'm wondering what is the best method to train Tesseract (kind of text/TIFF and so on) for a particular kind of documents, with these particularities:
At the moment I used standard trained datas, I detect the entire text and I extrapolate the codes with some regular expressions. It's okay, but I've got errors sometimes, for example:
0 / O
L / I / 1
Please someone knowns some "tricks" to improve precision?
Thanks!

during training part of Tesseract, you have to make a file manually to give to the engine in order to specify ambiguous characters.
For more information look at the "unicharambigs" part of the Tesseract documentation.
Best Regards.
